Straight Pipe or H Pipe?

I got a quote from a guy today at a local muffler shop and he wanted to do two straight pipes for true dual Flowmaster 40's. What would be the difference as far as sound and power between the straight pipe and the H pipe? And how much more would it cost for a fabricated h pipe?

There's not going to be a big power difference between the two. Due to our engines being even firing we don't need the crossover to equalize backpressure. The only real difference you'll notice in performance is a small loss of low end torque if you go with a larger diameter tube size (stock is 2.25"). Everyone else has basically told you about the sound differences between divorced pipes and an h pipe. Head over to Youtube or check the exhaust sticky if you want to hear what the difference midpipe/muffler combos sound like.

what most of you are forgetting is that the OP is in an s197 which is the 4.0L....which has a raspier tone then a new edge. the h-pipe is noticable on them

idk about that. 4.0's sound smooth as a bmw to me. my friend has a 4.0 with American thunder duals and it only sounds a little raspy at idle but on the throttle its a much smoother sounding engine. i actually kinda like it because everyone knows its a six because its such a smooth v6ish sounding exhaust, and i think v6's sound better smoother.

again it's an opinion thing..if you think they sound smoother then more power to you. i hear more rasp, and when i hear one with a nice h pipe it makes me smile
